The Atlas carabiner with an automatic triple-action twist lock closure for maximum security. The new Atlas is notable for its superior strength—which approaches the strength of some steel carabiners, but at a fraction of the weight—and its oversized design which makes rigging easy, even while wearing gloves. This combination of strength and ease of use makes it an ideal carabiner for search and rescue applications. We recommend the 3Lock system if you intend to use an auto-locker as your general belay biner.
